Bodycote Testing Group provide one of the most comprehensive range of corrosion testing facilities available. Amongst this range are: -

· Sour Service Corrosion Testing, both Small Scale Tests and Full Ring Testing

· Consultancy

· Materials Selection

· Electrochemistry

· Autoclave Testing

· Inhibitors

· Environmental Conditioning / Salt Spray Testing

· Routine Tests

· Group Sponsored Projects

· Weldability Trials
Sour Service Corrosion Testing

Testing in Hydrogen Sulphide containing environments is undertaken in a number of the Group's laboratories. The most extensive facility is situated at the Bodycote Corrosion Centre, where our specialist sour service centre has been established.

The laboratory holds UKAS accreditation for the following: -

· Full Ring Testing (OTI 95 635)

· SSCC (NACE TM 0177, EFC 16 and 17)

· HIC (NACE TM 0284)
Full Ring Testing

The laboratory is capable of handling large numbers of samples, up to 52” diameter in the case of full ring tests.
Consultancy

The Bodycote Corrosion Centre also offers a Consultancy service on corrosion problems. Several senior consultants with many years’ experience are available to help and advise on corrosion or materials selection queries.

Highly experienced and qualified engineers routinely undertake corrosion studies within the Group.
Materials Selection

Correct material selection when a process employs aggressive environments is essential.

At the Bodycote Corrosion Centre, materials selection is regularly undertaken with facilities available for handling the most aggressive chemicals, such as Hydrofluoric acid at elevated temperatures.

Environmental cracking tests can also be performed in similar environments.
Electrochemistry

Facilities are available for conducting electrochemical corrosion tests at ambient and elevated temperatures and pressures.

The available techniques include Zero Resistance Ammetry (ZRA), Linear Polarisation Resistance (LPR), Potentiostatic and Potentiodynamic Polarisation. These techniques can be applied to the study of general corrosion, pitting attack, galvanic corrosion, and preferential weld corrosion.
Autoclave Testing

Corrosion resistant autoclaves are available, for performing corrosion tests at elevated temperatures (up to +250°C) and pressures (up to 250 bar).

The autoclaves can be applied to studies in sour (H2S) and other aggressive environments. The autoclaves include facilities for gas changing, sampling and oxygen monitoring at ppb levels.

Several autoclaves from 1 litre to 10 litres are available ensuring that large numbers of samples can be accommodated. Electrochemical, Stress Corrosion Cracking and Pitting / Crevice Corrosion Tests can be undertaken within the autoclaves
Inhibitors

Inhibitor screening and evaluation is another facility available within Bodycote Corrosion Centre. Testing using electrochemical techniques and hydrogen permeation is currently employed to determine the correct choice of inhibitor to give protection in a particular process or environment.
Environmental Conditioning / Salt Spray Testing

A number of environmental test chambers are available within the Group. Salt Spray Testing and CASS Testing is performed on a routine basis.

Specialist chambers can be constructed to accommodate unusual requirements and test conditions.
Routine Testing

A wide variety of routine tests can be undertaken to evaluate the corrosion resistance of materials to general corrosion, pitting corrosion, selective leaching, crevice corrosion and intergranular attack.

These tests are normally performed in accordance with standard ASTM, NACE, DIN, British and ISO methods. Interpretation of test results and advice on the most appropriate test method is available from our team of corrosion engineers.

Bodycote Corrosion Centre is staffed and managed by corrosion specialists who are committed to playing a full role in the development of new test methods and standards. The Group works with clients and various industry bodies such as NACE International, ISO and EFC.
Group Sponsored Projects

The Bodycote Corrosion Centre is currently running a Group Sponsored project entitled ‘Accurate Assessment of Material Susceptibility to SOHIC for Line Pipe and Pressure Vessel Steels’.
Weldability Trials

The Bodycote Corrosion Centre offers a full Weldability Trial Service, this includes manual and automatic welding, mechanical and corrosion testing.
